Deflagration to detonation transition and detonation structure in diethyl ether mist/aluminum dust/air mixtures

► New insights into the DDT and detonation structure in DEE mist/aluminum dust/air mixtures. ► The detailed run-up distances of DDT in DEE mist/aluminum dust/air mixtures are obtained. ► Detonation in DEE (295 g/m3)/air mixture has a double-headed spinning structure. ► Detonation in DEE (314 g/m3)/aluminum dust (230 g/m3)/air mixture has a single-headed spinning structure.
